Description Hemant Kumar 2018-08-24 15:29:09 UTC

After https://github.com/openshift/origin/pull/20663 is merged, then node object will no longer be deleted when a node is shutdown. 

This will cause all volumes from shutdown node to be not detached and hence pods can not be migrated from the shutdown node. This is a regression from 3.9 and 3.10.

The upstream issue is being tracked - https://github.com/kubernetes/kubernetes/pull/67419

This BZ should be a 3.11 blocker.

fixes the upstream issue : https://github.com/kubernetes/kubernetes/pull/67847

Comment 2 Hemant Kumar 2018-09-05 20:50:10 UTC

We decided to not fix this in 3.11 and the default behaviour will be to not detach volumes. We will have to document this behaviour though.

I will create a JIRA issue for myself/doc team to address that.
